Title: Process for the polymerisation of diolefins
IPC: C07C2/46
Filed: 1959-07-15
Abstract: Diolefines are polymerized to waxy polymers at below 100 atmospheres in the presence of a catalyst formed by reaction between a titanium tetrahalide and an aluminium trialkyl or dialkyl hydride such that the atomic ratio Al/Ti is 2 to 3,:1. The diolefine may be butadiene or isoprene.  The catalyst may be formed by mixing in the required proportions or using excess of one reactant and adjusting the ratio by addition of the other before polymerization, with or without separation of the solid intermediate.  A diluent may be present, e.g. hexane, heptane, cyclohexane, gasoline, benzene, toluene or chlorobenzene. Temperatures of 30-100 DEG C. are used and pressures of 3-10 atmospheres though subatmospheric pressure can be used.  In the examples butadiene is polymerized in the presence of (1) titanium tetrachloride and diisobutyl aluminium hydride in benzene, (2) titanium tetrabromide and diisobutyl aluminium hydride in benzene, (3) titanium tetrachloride and triisobutyl aluminium in benzene and (4) titanium tetrachloride and diethyl aluminium hydride in benzene.ALSO:Diolefines are polymerised mainly to liquid polymers at below 100 atmospheres in the presence of a catalyst formed by reaction between a titanium tetrahalide and an aluminium trialkyl or dialkyl hydride such that the atomic ratio Al/Ti is 2-3,5:1. Butadiene and isoprene may be polymerised, the former giving mostly cyclododeca-1, 5, 9-triene.  The catalyst may be formed by straightforward mixing or by using excess of one reactant and adding sufficient of the other before the polymerisation to give the desired ratio, with or without separation of the solid intermediate.  The titanium halide is preferably the chloride ; suitable alkyl groups in the aluminium compound are ethyl, propyl, isobutyl, hexyl and octyl. The reaction is preferably effected in a diluent such as hexane, heptane, cyclohexane, gasoline, benzene, toluene, or chlorobenzene. The temperature may be 30-100 DEG C. and the pressure suitably 3-10 atmospheres though subatmospheric pressures may be used.

Title: Sequential pure fluid amplifier
IPC: F15B21/02
Filed: 1963-06-19
Abstract: 1,003,731. Fluid amplifiers. SPERRY RAND CORPORATION. June 19, 1963 [June 29, 1962], No. 24421/63. Heading G4B. [Also in Division G3] Fluid, which may be gaseous or liquid, entering a chamber 11 by way of a nozzle 13 flows to a drain aperture 14 and enters a reset passage 20 to cause a jet from a nozzle 21 to deflect the main stream issuing from the nozzle 13 into an outlet 15‹. A feedback passage (not shown, but corresponding to feedback passages 16<SP>4</SP>, 16<SP>5</SP> from other outlets 15<SP>4</SP>, 15<SP>5</SP>) terminating in a nozzle 17‹ pointing radially inwardly near the top of the chamber 11 provides a jet to hold the main stream deflected into the outlet 15‹. In the embodiment shown, ten outlets 15‹ ... 15<SP>9</SP> are provided and each has a feedback passage 16‹ ... 16‹ terminating in a nozzle 17‹ ... 17<SP>9</SP>, but more or less outlets may be provided. Below the plane in which the nozzles 17‹ ... 17<SP>9</SP> lie is a second set of nozzles 19‹ ... 19<SP>9</SP> connected by passages 18‹ ... 18‹ to the passages 16‹ ... 16<SP>9</SP>, a passage 16" being connected to a passage 18<SP>n</SP> + 1 and nozzle 19<SP>n</SP>+1, and so on. The arrangement is such that fluid issuing from a nozzle 19<SP>n</SP> + 1 tends to deflect the main stream from an outlet 15<SP>n</SP> to the next outlet 15<SP>n</SP>+ 1 but is ineffective to do so in the presence of the more powerful jet from the nozzle 17<SP>n</SP> which maintains the discharge at the outlet 15<SP>n</SP>. A sleeve 22 over the nozzle 13 may be depressed through a key 25 and timer 26 to render the nozzles 17 ineffective to control the main stream which is then switched from one outlet 15 to the next by the corresponding nozzle 19. The period for which the timer holds the sleeve 22 determines the number of outlets through which the main stream is switched. If the sleeve 22 is depressed further it renders the nozzles 19 inoperative, and the reset passage 20 then directs the main stream to the outlet 15‹. Several units may be coupled together as a decade counter. Pure fluid control means may be used in place of the sleeve 22.
